A 73-year-old female with a history of HTN, CAD s/p CABG, MR s/p MVR, HFrEF, AF, and ESRD has had 6 admissions to the hospital for acute on chronic systolic heart failure over the past year. Her cardiologist decided to perform a right heart catheterization to evaluate her filling pressures and cardiac output. Her pulmonary capillary wedge pressure (PCWP) resulted at 27 mmHg. All of the following are causes of an elevated PCWP EXCEPT.

What is the name of the compound with the formula As2O6?

A 77-year-old female with a history of HTN, CAD s/p PCI, HFpEF, and COPD was admitted with acute on chronic hypoxic respiratory failure secondary to community acquired pneumonia. Despite treatment with antibiotics the patient developed worsening respiratory failure requiring intubation and mechanical ventilation in the ICU. During her initial work-up in the ED a troponin was drawn which came back at 148 ng/L. It continued to uptrend as her condition worsened and plateaued at 256 ng/L before starting to downtrend. All of the following may be causes of a type II MI related to “demand ischemia” EXCEPT.

A 92-year-old female with a history of HTN presents to the ED with syncope. She is found to have a HR of 35 beats per minute with a BP of 88/44 mmHg. She endorses lightheadedness and dizziness, as well as some nausea. Dopamine is ordered for positive chronotropy.At what dose does dopamine stimulate beta 1 adrenergic receptors increasing heart rate and myocardial contractility?

An 88-year-old female with a history of sick sinus syndrome with a tachy-brady pattern presents to the ED with fatigue, weakness, and near-syncope. While having periods of bradycardia her blood pressure drops to 68/42 mmHg. A temporary transvenous pacemaker wire is inserted. Which of the following temporary pacemaker settings would be considered a “sensing” mode?

An 89-year-old male with a history of HTN, hypertrophic obstructive cardiomyopathy (HOCM), and critical aortic stenosis is being considered for a transcatheter aortic valve replacement (TAVR). Prior to his procedure he presents to the ED with shortness of breath, fever, lightheadedness, and overall fatigue. CXR shows evidence of a right lower lobe pneumonia. Vital signs are as follows: temp 101.8, HR 129, RR 27, BP 82/50 mmHg, and O2 sats of 84% on RA which improve to 93% on 4L NC. He is having frequent ectopy on telemetry with a few episodes of non-sustained ventricular tachycardia.  Which of the following is the BEST choice for vasopressor support given his history and current clinical situation?

An 83-year-old male who was on the telemetry unit for a heart failure exacerbation has been transferred to the intensive care unit due to new onset atrial fibrillation with a rapid ventricular response. He was given a diltiazem bolus followed by a continuous diltiazem infusion without successful rate control. It has been less than 48 hours and direct current cardioversion is being considered. The success of electrical cardioversion is inversely proportional to which of the following?

A 77-year-old male with a history of HTN, CAD s/p CABG x4, HFrEF (EF 25%), and CKD is admitted to the cardiac ICU with cardiogenic shock. He is started on Dobutamine at 5 mcg/kg/min. A bedside swan-ganz catheter was placed in order to obtain hemodynamic information. Cardiac output and index are measured by which of the following techniques?

A 42-year-old male is admitted to the ICU following a cardiac arrest thought to be caused by a drug overdose. Following return of spontaneous circulation (ROSC) he has not shown any signs of purposeful movement and is exhibiting severe myoclonus. His core temperature is 101.3 ⁰ and targeted temperature management (TTM) is initiated. Which of the following is NOT a potential complication of TTM?

A 79-year-old female with a history of recurrent pulmonary embolism on lifelong anticoagulation with apixaban is undergoing an elective catheter ablation for SVT. Shortly after the procedure the pt complains of new onset shortness of breath and chest pain. A STAT echocardiogram is ordered and reveals a moderate pericardial effusion along the right ventricular wall with no evidence of pericardial tamponade. All of the following are potential etiologies of pericardial effusion EXCEPT.
